* Reenable AES-NI in libcryptotb2024-09-061-5/+8
| | | | | | | | | | | | | | | | | | | The OPENSSL_cpu_caps() change after the last bump missed a crucial bit: there is more MD mess in the MI code than anticipated, with the result that AES is now used without AES-NI on amd64 and i386, hurting machines that previously greatly benefitted from it. Temporarily add an internal crypto_cpu_caps_ia32() API that returns the OPENSSL_ia32cap_P or 0 like OPENSSL_cpu_caps() previously did. This can be improved after the release. Regression reported and fix tested by Mark Patruck. No impact on public ABI or API. with/ok jsing PS: Next time my pkg_add feels very slow, I should perhaps not mechanically blame IEEE 802.11...
* Add a few missing endbr64 to libcryptotb2024-02-241-0/+2
| | | | | | | | gcm_{gmult,ghash}_4bit(), aesni_ccm64_decrypt_blocks(), aes_cbc_encrypt(), and aesni_xts_{en,de}crypt() were overlooked in previous passes. Found with a diff for ld.lld by kettenis ok kettenis
* Replace uses of endbr64 with _CET_ENDBR from cet.htb2024-02-241-4/+4
| | | | | | | | | cet.h is needed for other platforms to emit the relevant .gnu.properties sections that are necessary for them to enable IBT. It also avoids issues with older toolchains on macOS that explode on encountering endbr64. based on a diff by kettenis ok beck kettenis
* Avoid a four-byte overread in gcm_ghash_4bit_mmx() on i386tb2024-01-241-1/+1
| | | | | | | This is a variant of the same logic error fixed in ghash-x86_64.pl r1.6. The code path is only reachable on machines without FXSR or PCLMUL. ok jsing
* Avoid a four byte overread in gcm_ghash_4bit() on amd64.jsing2024-01-241-1/+1
| | | | | | | | | | | | | | The assembly code for gcm_ghash_4bit() reads one too many times from Xi, resulting in a four byte overread. Prevent this by not loading the next value in the final iteration of the loop. If another full iteration is required the next Xi value will be loaded at the top of the outer_loop. Many thanks to Douglas Gliner <Douglas.Gliner at sony dot com> for finding and reporting this issue, along with a detailed reproducer. Same diff from deraadt@ ok tb@

* Make internal header file names consistenttb2022-11-269-17/+17
| | | | | | | | | | | | | | | | Libcrypto currently has a mess of *_lcl.h, *_locl.h, and *_local.h names used for internal headers. Move all these headers we inherited from OpenSSL to *_local.h, reserving the name *_internal.h for our own code. Similarly, move dtls_locl.h and ssl_locl.h to dtls_local and ssl_local.h. constant_time_locl.h is moved to constant_time.h since it's special. Adjust all .c files in libcrypto, libssl and regress. The diff is mechanical with the exception of tls13_quic.c, where #include <ssl_locl.h> was fixed manually. discussed with jsing, no objection bcook

* Explicitly export a list of symbols from libcrypto.jsing2016-12-211-1/+4
| | | | | | | | | | | | | | | | Move the "internal" BN functions from bn.h to bn_lcl.h and stop exporting the bn_* symbols. These are documented as only being intended for internal use, so why they were placed in a public header is beyond me... This hides 363 previously exported symbols, most of which exist in headers that are not installed and were never intended to be public. This also removes a few crusty old things that should have died long ago (like _ossl_old_des_read_pw). But don't worry... there are still 3451 symbols exported from the library. With input and testing from inoguchi@. ok beck@ inoguchi@

While there, turn it from an array of two 32-bit ints into a properly aligned 64-bit int. Use of OPENSSL_ia32_P is now restricted to the assembler parts. C code will now always use OPENSSL_cpu_caps() and check for the proper bits in the whole 64-bit word it returns. i386 tests and ok jsing@
